Question 1 of 5
CALCULATE FLOW RATES IN DROPS PER MINUTES: Order: Zosyn 1.3 g in 100 mL D5W IVPB 98h to infuse over 30 min. Drop factor: 60 gtt/mL. Determine rate in gtt/min.
Correct Answer: C
Rationale: The correct answer is C (200 gtt/min).
To calculate the flow rate in drops per minute, you first need to find the total volume to be infused: 1.3 g/100 mL. Next, convert 30 minutes to 1 hour by dividing 30 by 60, giving you 0.5 hours.
Then, divide the total volume by the infusion time in hours to get the rate in mL/min. Finally, multiply the rate in mL/min by the drop factor (60 gtt/mL) to get the flow rate in drops per minute.
Therefore, the correct answer is 200 gtt/min.
Choices A, B, and D are incorrect as they do not follow the correct calculations and steps as outlined above.
